Casey Kasem's kids claim they're being kept from ailing dad

Casey Kasem's voice has been heard in homes around the world, but now it seems his own family might not be welcome in his home.

Family members of the 81-year-old radio personality have stated that his health is deteriorating due to Parkinson's disease. His children, brother and others close to him throughout his life also claim Casey's wife, Jean Kasem, is keeping them from seeing him. So on Monday, Oct. 1, family and friends staged a protest outside of Casey and Jean's L.A. home.

Kerri Kasem, one of Casey's daughters from his first marriage to Linda Myers, told L.A.'s ABC7 her stepmother will not answer her phone calls and tells her and siblings Mike and Julie to go away when they knock on the door. "He can't really speak, but he knows we're there," she said. "And last time we saw him, he could shuffle a little bit. He had a hard, very hard, time walking. He was just deteriorating due to Parkinson's disease."

The radio legend's brother Mouner Kasem is also concerned. "I've got a feeling I might not see him again, and that's why I'm here," he said.

Kerri, Mike and Julie say they do not have a relationship with their stepmother, who married Casey in 1980. Jean and Casey have one daughter together, Liberty, a singer-songwriter.

It's not just family, though, who is concerned about the radio personality. Chuck Olsen, a friend of Kasem's for 63 years, told ABC7 no one has been in touch with the star since April 2013.

Casey's daughter Kerri insists they don't want to see the ailing legend in hopes of one day inheriting his fortune. "We don't want to see him go and not say goodbye and not love him and not support him," she said. "We don't know how long he has."
